Answer 1

$( {1}^{3} + {2}^{3} + {3}^{3} + {8}^{3} ) {}^{ \frac{ - 5}{2} } \\ \\ = > (1 + 8 + 27 + 64) {}^{ \frac{ - 5}{2} } \\ = > (100) {}^{ \frac{ - 5}{2} } \\ = > ( \frac{1}{100} ) {}^{ \frac{5}{2} } \\ = > \frac{1}{(100) {}^{ \frac{5}{2} } } \\ = > \frac{1}{ ({10}^{2}) {}^{ \frac{5}{2} } } \\ \\ = > (\frac{1}{10}) {}^{5}$
